This invention relates to a feeding device for the stora countin mechanisms in calculating machines in which these counting mechanisms in a manner known initself .I' are arranged on the periphery of a rotatable drum, this drum being rotated about its axis under the influence of the aper carriage, as it jumps from column to co umn during the'working operation, in such a way C 10 thatat each jump of the paper carriage the next countin mechanism moves into the workin sition.

The 0 ect of the invention is to construct the feeding device that serves for carrying 15 out the above-mentioned operation, that is to say, the device for intermittently locking and releasing the drum, which is set in rotation by spring power during the working operation, in sue a way that an absolutel reliable action is obtained and that disad vant'ageous shocks during the working operation and also during the return of the counting mechanism drum into the initial position or into apreceding sition are obviated.

In order to attain t 's aim the feeding device for the stora e counting mechanisms of calculating mac 'nesaccording to the resent invention is essentially characterized y the fact that the stops provided on the drum forthe locking. and release thereof in the working positions of the counting mecharound the axis ofthe drum, and the necessary common abutment member for the stops, for checking the movement of the drum, is displaced, under the action of the paper carriage, in a radial or approximately radial direction.

One constructional form of the feeding device according to this invention is shown in side elevation in the accompanying drawing.

On a bar a of the paper carriage of the calculating machine are arranged stops or riders b at distances from one another correspondin to the division into columns of the form to written.

- By these stops 6, when the jumpingmovement of the paper carriage from onecolumn msms'are arranged step-wise in spiral form tends to rotate towards PATENT OFFICE ANTON BLUE, OI'JZ, G, ASSIGNOB TO FIRE wmnm 'VOB-K. WINKLHOI'EB & TAEN'ICKE A. G, 01" SCEOENAU, um

c is rotated thro h a definite angle, and with it a vertical sha t d car the star wheel 0. The shaft d transmits its rotation through toothed wheels e and f to a screw-threaded. spindle 9. By the rotation of the spindle g a carriage i, mounted thereon by means of an internal screw thread, and guided vertically in a separate guide h,.is axiall displaced, and with it an abutment r k, transversely slidable therein for the stepped stops'm arranged on a disc ion the counting mechanism drum, which is rotated by a sprlng z.

The transmission ratio between the toothed wheels e and/f is so selected that when the carriage jumps the abutment k moves out of reach of the stop m that was previously bearing against it and into the path of the next stop m, so that the rotation of the drum is checked in the succeeding counting mechanism position.

The abutment k, with the end n opposite to the face which with the abutment m, slides on a bar 0, which bears against a member 1) consisting of resilient material such as india rubber, so that the impact of the stops m against the bar k is transmitted. by the latter to the bar 0, which bears against the cushion p. This a ment prevents the impact of the sto from affecting the spindle g by which the at k is carried.

When the drum and the disc 1 are being returned in the direction of the arrow :1, the spindle tends to lower the carriage i with the bar 1% at a uniform speed. Since the disc lis not a smooth spiral curve, however, but is stepped, the peripheral surfaces of these steps m would at times exert an upward pm.- sure upon the bar 70. In order to prevent j nmming, therefore, the spindle g is made capable of yielding in an upward direction, and a spring blade q is provided for the pu of pressing it towards the disc. Y

In order to protect the drum against rebounding or recoil movements when the sto s m strike against the abutment 1: during t a working movement a pawl r is provided, whichis so influenced b a spring a that it e left about its axis t, and bears with an arm u against a slide '0,

operatively connected with the .-paper-carriage returning device.

During the working movement of the drum in the direction of the arrow 3/, this pawl 1 in each of'the stationary positions fixed by the stop m and the abutment is, snaps in the manner illustrated behind the associated counting mechanism shaft w and thus prevents any backward movement of the drum. w During the return of the drum to theinitial position or a preceding position the slide '0 is shifted towards the right by the returning device, and consequently, by means of this slide, the pawl 1' is held by its arm u in the released position, that is to say, rocked towards the right.
